Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

Embryonic morphological development is delayed in live pregnancies ending in miscarriage, according to a prospective cohort study from the Netherlands. Among over 600 singleton pregnancies, those ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

As the climate changes, scientists are concerned about how well plants and animals will adapt to rapid warming. A new ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in the body.

A "synthetic" embryo with a brain and beating heart has been created by British scientists. It features the foundations of all the body's organs, including neural and gut tubes that protect the ...
